Cranfield's research on improved soil management planning through enhanced spatial information has influenced policy development, allowed the adoption of new approaches to soil mapping, and enhanced the management of strategically important land assets. The research has provided key input to policy development nationally, within the European Union and across the globe. It has developed new technologies which have been used to survey soils at the scale of complete countries, saving significant cost and survey time compared to conventional methods. Cranfield's modelling has also supported the management of strategic land assets such as military training areas, and soil-related geohazards related to road networks and other linear infrastructure at the regional and national levels.
The applied use of earthworms in soil restoration, bio-monitoring, agro-ecosystems and organic waste management has had wide-reaching impact on the commercial sector and the public. A variety of commercial groups (such as the Forestry Commission and BAE Systems) have benefitted from this research in both the UK and abroad. In addition to this, earthworm research has also reached the public domain through outreach activities and media coverage. For example, this UoA was involved in a National Open Air Laboratories campaign. Our earthworm identification guide produced in collaboration with the Natural History Museum in London has now been widely distributed and used.
Impact: Policy, Economic: Improved soil fertility and crop yield, reduced erosion and flood and reduced greenhouse gas (GHG) emissions from waterlogged and compacted soils.
Significance: A decrease in soil structural quality as a result of compaction or erosion decreases grain yield substantially. Novel indicators that assess visual structure and biological quality allow soil samples to be easily assessed for possible improvements in quality.
Beneficiaries: Farmers, agronomists, environmental bodies e.g. Scottish Environment Protection Agency (SEPA), water companies and waterway authorities, local government, policy makers and the general public.
Attribution: Dr. Ball and Prof. Watson (SRUC)
Reach: The visual structure index uses a simple colour guide that has been widely distributed and promoted in nine countries overseas and three continents.
The way in which UK upland hay meadows are managed and restored to conserve botanical diversity has been largely determined by research carried out at Newcastle University. Increased post-war agricultural production has converted most species-rich upland hay meadows to species- poor rye-grass grassland so that today only 1070 ha (hectares) undisturbed hay meadow remains. The Newcastle research has been used by Natural England (an executive non-departmental public body responsible for England's natural environment) to produce targeted management prescriptions for 2500 ha of farmland in northern England and has informed National Park and AONB (Area of Outstanding Natural Beauty) management on best practice for successful restoration of hay meadows. The research has ensured the successful restoration of more than half of the remaining upland hay meadows in England.
The EKG technology developed by Newcastle has launched an entirely new spectrum of applications for geosynthetic materials and has resulted in changing established practice in civil, construction and mining engineering. The commercialisation of the technology, linking industry to applications of EKG products and processes, has been driven by the spin-out company Electrokinetic Limited. Amey, a leading international infrastructure services provider, incorporated the EKG technology into £1M projects for Network Rail and the Highways Agency in 2011-12. The end results were a 30% cost saving and 40% reduction in CO2 compared to established methods. The new range of EKG products has been recognised by British Standards, leading to the revision of BS 8006 for reinforced soil in 2010.
Research by Dr Switzer since 2009 has led to scale-up and commercialisation of a new smouldering combustion-based remediation technology: Self-sustaining Treatment for Active Remediation (STAR). STAR is sold commercially by SiREM, a division of Geosyntec Consultants, Inc. that has an exclusive worldwide licence. Since its commercial launch in 2010, STAR has [text removed for publication] and now employs 5 staff. Clean-up rates for STAR far exceed those of other methods, achieving 99.9+% destruction of contaminants in the soil and delivering cleaned soil suitable for reuse.
New analytical methods have been used in commercial applications for the 2012 Olympic Park to measure petroleum hydrocarbons in soil. Cranfield developed techniques, in collaboration with Eurofins, to meet the needs for contaminated land risk assessment and enable the selection of remediation strategies. Decision-support tools were developed for risk management and environmental rehabilitation of contaminated sites. The tools contribute to end-user confidence in remediation technology, reduced remediation costs and minimised waste disposal to landfill with subsequent savings in CO2 emissions. Our research laid a road map to demonstrate risk reduction and provided practical and cost efficient soil quality management tools.
